Gabbert remains in the concussion protocol but is being evaluated, Jim Wyatt of the Titans' official site reports.
Coach Mike Vrabel elaborated on Gabbert's health Monday, stating "once I get a report from the doctors, and Blaine sees the doctors, we'll have a better idea on what his availability is going to be and what it might look like." Gabbert exited the Titans' Week 3 matchup early in the game, and with Marcus Mariota still battling an elbow injury, he may draw a start Week 4 if he can clear the league's protocol.
